Upstream PCIe SSD Datasheet
Rev 1.0 November 2011 Page 5
1.0 PRODUCT DESCRIPTION
1.1 PRODUCT OVERVIEW
Upstream is designed to break the throughput bottleneck in the storage subsystem by
removing the bandwidth limitation of the SATA bus. The PCIe (Gen.1) x8 interface used by
Upstream supports 2GB/sec bandwidth, more than 6 times that of the SATA-II 3Gbps bus, and 3
times faster than the SATA-III bus.
Using the latest NAND flash memory chips and most verified LSI RAID controller, Upstream is
able to support Max. Read speeds of up to 1.0GB/sec. It also enables Max. Write speeds as fast
as 900MB/sec without the volatile DRAM cache memory. Upstream, which houses four discrete
SATA SSDs, comes in a custom formfactor measuring 167.65x 98.4 (mm).
This small formfactor now can be fitted into the 1U/2U/3U rack mount storage server with the
RISER card, which is one of the great advantages over the competitors’ products
